Abstract (en)
[origin: EP0340485A2] A noise suppressing arrangement in the form of an interface is provided between a data transfer circuit and a driver associated with a display unit VFD tube. The driver and power supply circuits associated with the display unit feature improved arrangements which attenuate surges and spike. The voltage appearing on the grid of the VFD is controlled by a circuit which is responsive to a signal produced by microcomputer which controls the illumination and which induces changes in the voltages applied across the filament of the VFD. The level of illumination can be automatically controlled by light sensor and illumintion levels above default values are automatically reset to optimal values each time the system is initially energized.
